Booking flights in 2026? Florida airports sweep top 5 nationally for website security, study reveals

• Miami International Airport has the most secure website of any major airport hub in America, providing greater protection for travelers' personal information, like credit card details and travel records. 
• Fort Lauderdale–Hollywood International Airport and Orlando International Airport claimthe third and fourth spots with impressive security scores of 92.5 and 90, respectively. 
• Tampa International Airport has the least secure website among Florida's major airports.

Miami International Airport has the most secure website among major U.S. airports, a new study has revealed. 

Digital privacy company VeePN tested website security at America's 31 large airport hubs, with each rated for security headers and SSL security. Security headers are a crucial component of any website, helping prevent various cyberattacks. Sites with excellent SSL security ensure your data is more secure and less vulnerable to hackers. The airports were analyzed and given a grade for each metric, with an average overall score out of 100 then calculated. 

Table: America’s large airport hubs with the most secure websites 

Florida airports performed well in the rankings. Miami, Fort Lauderdale, and Orlando all landed in the top 10 most secure websites, making Florida the standout state for airport digital security nationwide.

Miami International Airport takes the top spot with an impressive score of 97.5 out of 100. Visitors to the Miami Airport website are the safest thanks to a top SSL security grade of (A+).  

Fort Lauderdale–Hollywood International Airport secures third place with a security score of 92.5, rating higher for security headers (A). 

Orlando International Airport scored exactly 90, tying for fourth place. The airport earned a B grade in security headers and an A+ grade in SSL security.

Tampa International Airport was the outlier in Florida, ranking among the airports with the least secure websites. While it scored a respectable B for SSL security, it was pulled down significantly in the ranking due to a poor performance in security headers (D).

Phoenix Sky Harbor International Airport ranks as the joint least secure airport website with a score of just 50. The Arizona hub failed completely with an F in security headers, dragging down its overall score. 

The bottom spot was shared with Daniel K. Inouye International Airportin Hawaii.Despite a respectable B for SSL security, its terrible F grade in security headers proved a major factor in its poor overall performance in the study.

Anthony Brown, Web Software Developer at VeePN, commented on the findings, "These results show significant variation in airport website security across the U.S. The difference between the highest and lowest scores is quite stark at almost 50 points. 

"Many of the airports with lower scores could make simple improvements to boost their security considerably. Updating security headers is a straightforward fix that would benefit many of the lower-ranked websites."  

SSL Labs grades proved a bright spot for most airport websites with 23 of the 31 airports receiving an A or A+ grade in this critical security category that evaluates encryption protocols used to protect sensitive data between travelers and airport websites. 

Security headers told a completely different story. Twelve airports failed outright. 

Brown added, “These F grades in security headers highlight a widespread vulnerability among many of America's busiest air travel hubs and point to a critical area where numerous facilities could make straightforward improvements to boost their overall website security and better protect travelers' personal information including credit card details and travel records. 

"Airport websites often handle sensitive traveler information and reservations, making their digital security particularly important. The best-performing airports demonstrate that achieving high security standards is possible, and others should follow their example.”

• Security Headers for a grade relating to security headers 
• SSL Labs for an SSL security grade
• Each airport was given an average score based on the grades and ranked.
